You are correct. It was a 1st printing and a long time ago.I'm assuning your 1st books were the 1st printing. There is a known issue that the 1st printings of the core books had the glue giving up. I have the 1st printings of every book I've bought, only my PHB started falling apart because that's the book i use the most. I bought a new copy recently, and it's pretty funny finding the differences between the 2 books.
my dmg and mm are still doing fine all these years later but I am easy on game stuff.
it looked like my 1e stuff went through a war , but that is due to high school and college allowing for more time gaming. They were always in a backpack, in the car in my hands....
and they are still quite solid!
